CAMERA-STAND.

Specification of Letters Patent.

Patented April 9, 1907.

Application filed February 16,1906. Serial No. 301,492.

To ctZZ LU/b07771 it puny concern:

Be it known that I, KNUD NELSON, of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Camera-Stands, of which the following, when taken in connection with the drawings accompanying and forming a part hereof, is a full and complete description, sufficient to enable those skilled in the art to which it pertains to understand, make, and use the same.

a The object of this invention is to obtain an adjustable camera-stand which when set will provide a rigid table on which a camera may be placed for photographers use.

I I have illustrated a device embodying; my invention in the drawings attached hereto and forming a part hereof, in whieh--- Figurel is a side elevation of an adjustable camera-stand; and Fig.2 is a plan view of the operative parts thereof, showing the vertical parts in section on lines 2 2 of Fig. I

viewed in the direction indicated by the arrows.

A reference-letter applied to designate a given part is used to indicate such partl throughout the several figures of the drawings wherever the same appears.

A A A are the legs of the camera-stand.

B B are horizontal platforms, to which the l legs A A A are respectively secured, as by screws (0 a a. here three legs are used 1n the camera-stand embodying this invention,

as is shown in the drawings, Figs. 1 and 2, the platforms B B are respectively preferably triangular in shape.

0 is the top of the camera-stand, on which acamera may be placed, and D is a horizontal table-top, to which one end of the top C may be secured, as by the bolt or pivot (Z.

E is a triangular piece, preferably of wood,

attached to base F, and provided on the under side thereof with notchesff, arranged, respectively, to fit over the pin 6 in table I). When the end of the top O, which is adjacent to the piece E is raised, any desired one of the notches f f may be brought into engagement with the pin 6 and the slant of top C thereby determined. A slot is preferably provided in the end of the horizontal tabletop D in which piece a is placed. Base F and triangular piece E are not attached to top C or table-top 1) except by engagement of no tches f and pin 6 and the weight of the top C resting on base F.

G G G are vertical rods, preferably of wood, extending through the platforms B B. ltods G G G are attached at their upper ends to base II, and such base is secured on the under side of the table-top D,-and at their lower ends such rods are attached. to base I. The rods G G G move longitudinally in the holes in platforms B B, through which such.

rods extend, and thus the rods, together with the bases 11 I, table-top D, and top C, may be raised and. lowered when not set by the turning of the crank-shaft J and. crank in bearing K to wind or unwind the flexible connection L around a pulley M on the shaft J. Shaft J is rotatably mounted in bearing K on the lower one of the platfori'ns B B, and one end of connection is secured to pulley M on shaft J and the other end to base I.

N is a triangular-shaped lever loosely mounted on standard O.

To set the vertical rods G G G in a desired position, the triangular-shaped metal lever-N is forced into a horizontal position, so that the part a thereof in engagement with such vertical rods will force such rods outward sufliciei'itly to bind the rods in platforms B B, so that upward or downward movement thereof will not occur. The rods G G G are made to move freely in the holes in platforms B B when lever N is not in a horizontal position, and when such lever is forced into a horizontal position the portion of such. rods G G which are between the platforms B B will be so sprung out of a vertical position as to be locked securely in place against upward. and downward movement thereof.

0 is a standard on platform B, on which standard the lever N is supported when such lever is thrown out of a horizontal position.

Having thus described my invention, what I-claim as new, and desire to secure by Letters Patent, is

In a camera-stand two horizontal. platforms, legs connected thereto to support the same and space them the one above the other, parallel rods mounted in said platforms to move vertically through the same, and atop mounted on the upper ends of said rods, a lever lying between said platforms and said rods, and adapted when moved to approximately horizontal position between said rods to force the same from their parl allel position, thus causing the rods to bind l in the platforms and hold the top at any posi l tion of vertical adjustment. l KNUD NELSON. l In presence of CoRA AIADAMS, CHARLES TURNER BROWN.
